kubernetes国内镜像拉取

因国内访问不到goole服务器，只能拉取国内的镜像，这里以阿里云为例。

安装minikube时报failed to pull image "k8s.gcr.io/kube-apiserver:v1.13.4"。

原理：先拉取阿里镜像，再改名

docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/etcd:3.2.24

docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/etcd:3.2.24 k8s.gcr.io/etcd:3.2.24

1.准备脚本

先设置k8s镜像源

[root@localhost yum.repos.d]# cat kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=http://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=
gpgcheck=
repo_gpgcheck=
gpgkey=http://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg
        http://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg

[root@localhost yum.repos.d]# 

yum install -y kubelet-1.14.0 kubeadm-1.14.0 kubectl-1.14.0

后查看版本依赖

[root@localhost yum.repos.d]# kubeadm config images list
I0401 ::19.728564    version.go:] could not fetch a Kubernetes version from the internet: unable to get URL "https://dl.k8s.io/release/stable-1.txt": Get https://storage.googleapis.com/kubernetes-release/release/stable-1.txt: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
I0401 ::19.728628    version.go:] falling back to the local client version: v1.14.0
k8s.gcr.io/kube-apiserver:v1.14.0
k8s.gcr.io/kube-controller-manager:v1.14.0
k8s.gcr.io/kube-scheduler:v1.14.0
k8s.gcr.io/kube-proxy:v1.14.0
k8s.gcr.io/pause:3.1
k8s.gcr.io/etcd:3.3.
k8s.gcr.io/coredns:1.3.
[root@localhost yum.repos.d]# 

[root@localhost bin]# vi pullK8s.sh 

#!/bin/bash
KUBE_VERSION=v1.14.0
KUBE_PAUSE_VERSION=3.1
ETCD_VERSION=3.3.
DNS_VERSION=1.3.
username=registry.cn-hangzhou.aliyuncs.com/google_containers

images=(kube-proxy-amd64:${KUBE_VERSION}
kube-scheduler-amd64:${KUBE_VERSION}
kube-controller-manager-amd64:${KUBE_VERSION}
kube-apiserver-amd64:${KUBE_VERSION}
pause:${KUBE_PAUSE_VERSION}
etcd-amd64:${ETCD_VERSION}
coredns:${DNS_VERSION}
    )

for image in ${images[@]}
do
　　 new_image=`echo $image|sed 's/-amd64//g'` ##此处需删除“-amd64”,否则kuadm还是无法识别本地镜像
    docker pull ${username}/${image}
    docker tag ${username}/${image} k8s.gcr.io/${new_image} 
    #docker tag ${username}/${image} gcr.io/google_containers/${image} 
    docker rmi ${username}/${image} 
done

2.执行脚本

[root@localhost bin]# sh pullK8s.sh
